present invention has "for its object the provision of a relatively simple conveying apparatus intended for general use, but especially adapted for use in conneetlon with litter carriers of the type used in barns. As is well know-n horizontal swing ng cranes are now commonly used for carrying sections of'tracks for such litter carriers outside of the barn where the litter may be dumped over a relatively large and at a distance fronr the barn. Such cranes place a great deal of strainonfa barn 'struc ture'and the length of the track section that can thus be carried by a crane is limited to thestrain that a barn structure will stand and the elevation above the crane to which one or more supporting members therefor may be attached. As a great manybarns are of the shed type, it is very difficult and often impossible tomount a crane of this type thereon. p I

The invention includes -a structure 1n which a horizontalswinging crane may be sup-ported in such a manner as to reliei e a barn structure of substantially all strain and it is well adapted for use in connection with barns of the shed type in which thereis very little space above the door opening through which the litter carrier travels to and from the barn. t

This conveying apparatus also materially increasesthe distance a litter carrier may be conveyed from a barn. v

To the above end; generally stated, the invention consists of the novel devices and,

combinations of devices hereinafter described and defined. in the claims. I Inthe accompanying drawings5 which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings: Fig. 1 is a View showing a fragment of a barn structure in vertical section and also illustrating the invention diagrammatically; Fig. 2 is a view of'themast with the bridge sectioned-on the line 2'-2 of Fig. 1; Fig. 8 is a plan view of the mast and.

crane and also showing a portion of the bridge;

cross member of the mast'and adjacent portions of the track sections and bridge; I

Fig. '6 1s a fragmentary plan view of the strut andcrane as shown in Fig. 4-; and

Fig. 7 is a detail view partly in elevation and partly in section taken on the line 7 7 of Fig. 4, on an enlarged scale.

The numeral 8 indicates a barn structure having in its lower floor a'door opening'9 over which is a heavy header l0 and which door opening opens onto a barnyard l1. On the lowcrfloorof the barn Sis'a litter "carrier track 12 which leads to the door opening 9.

Reterrmg now in detail to the invention the numeral 13 indicates an*A-shapedmast spaced from the barn 8 and set fi'atwise parallel to the sideof said barn having the door openin The cross member of the mast 13 comprises a pair of timbers let and 15 secured one to each face of said mast. The legs of the mast 13 rest on concrete having embeddedtherein anchor straps 17 bolted' to said legs and rigidly holding-said mast in place.

A fixed track section 18 forms a continuation of the track section 12 and extends to the mastl3 and a horizontal swinging track section 19 extends outward of said mast, forms a continuation of the track section 18 "and attached thereto by a short "flexible track section 20 which permits horizontal swinging movement of said track section 19. The track section 18 is suspended by a plurality, of hangers 21 from abridge 22 in the form of a beam comprising rigidly connected longitudinally aligned tubular sections. One

end of the bridge 2:2 is rigidly secured to the 24 onto the bridge 22. I

The sections of the coupler 23 have integrally formed therewith laterally and horizon'tally extendedfianges 25 which bear'directly aga'i11st"the outer face of the barn 8 in front of the header 10 and are rigidly bolted to saidbarn and header, as best'shown opening 9 anddire'ctly in front of said door piers 16 header 1-0 by a coupler 23 and the otherend Lil Land

in Fig. l. The coupler 24 is also provided with laterally and horizontally extended flanges 26 which bear against the barn side of the mast section 14 and are rigidly bolted thereto.

A pair of diver- 7g brace irons 27 rigidly secure the track section 18 to the mast section let and hold said track section 20 against lateral movement during horizontal swing ing movement of: the track section 12) or when said track section is in a position out of alignment with the track section 1.8. A plurality of intermediate couplers 28 are applied to the bridge 22 at longitlulinally spaced. points and each. thereof is vertically and. longitudinally div ded and the sections thereof connected by draw-bolts which i rictionally clamp said sections onto the bridge 22.

A pair oit horizontally aligned tubular struts 29 extend t 'ansversely from opposite sides of the bridge 22 and are rigidly secured to the couplers 28 by having; their inner end portions mounted in sockets in said couplers and l rictionally held in position.

As shown, there are three pairs of struts 29 and the intern'iediate pair are son'iewhat longer than the end pairs lhereoit. (luy wires 30 have their ends anclmred in eyes on the sides oil the couplers 23 and 21 iT and their inlcrmediate portions extend. through holes in the struts 29 near their outer ends. A turn buckle 31 is interposed in each guy wire Pa) for holding the same taut. tlbviously the struts 29 and guy wires ill) securely hold and brace the bridge 22 against lateral buckling m ovement.

The track section 19 carried by a crane 32 comprising a beam made up of longitudinally aligned tubular sections similar to the bridge 22. The crane P2 is connected to the mast section 15 by a hinge 3?) for horizontal swinging movement. This crane 32 may be broiurht into longitudinal aligmnent with the bridge 22 or swung laterally to either side of this position.

The anchor member oil? the hinge 33 is rigidly bolted to the mast section 15. (.ln the outer end ot the Cl'ilillbi'iil a. coui ler ilithat is longitudinally and vertically divided and the sections thereof connected. by draw-bolts which trictionally clamp said coupler onto the crane 32.

Couplers 35 similar to the couplers 28 are applied to the crane 32 at longitudinally spaced points and struts 3G in the same air rangement as the struts 2.) are secured. to said couplers 35. A pair ot. guy wires 37 have their em s anchored to the eyes on the sides ot. the movable member of the hinge 33 and the coupler 34: and their intermediate portions are extended through holes in the struts 136 near the outer ends thereof. A turn buckle 38 is interposed in each guy wire 27. The struts 36 and guy wires 37 for the crane 82 serve the same purpose as the struts 29 and guy wires 30 for the bridge 22.

The bridge 22 and crane 82 are supported in substantially balanced relation from the top of the mast 13, the former by a group o'l supporting members 39 and the latter by a group ot supporting members 40. The supporting members 89 and lt) are in the form of wire cables and one of the ends of the supporting members 39 are secured in a. single eye-bolt 41 in the top of the mast 13 and projecting from the barn side thereof.

and their lower ends are connected by turn buckles l2, the one to an eye in the top of the coupler 23 and the others to eyes on the tops oil the couplers 28. It will thus be seen that the support members 39 extend in diverging relation from the top of the mast 13 and support the bridge 22 at longtiudi- 'nally s3aced points.

The supporting members l0 are identical with the supporting members 89 and have one oi? their ends attached to an eye 13 in the belt ll, on the opposite side of the mast 13 from the barn 8.

Turn buckles 4.4: connect the lower ends of the suopo-rtingn'iembers lO, the one to an eye on the top of the coupler 34k and the others to eyes on the tops of the couplers These supporting members ll) also extend in diverging relation from the top of the mast 13 but on the opposite side thereof from the supporting mem ers 39 and support the crane 32 at longitudinally spaced points.

It important to note that the eye 43 is located directly over the pivot member of the hinge 33 and that the flexible track section 29 is directly below the hinge 83 so that the track section 19, crane 32 and supporting;- members are held for horizontal swinging movement about a common vertical axis:

lly supporting the track 22 and crane 32 from an intermediate point in substantially balanced relation substantially all strain is removed from the barn structure 8 and only a relatively light upward strain is placed on the header 1.0 by the crane 32 and parts carried thereby.
